A neurotransmitter that is crucial to the brain's ability to differentiate between the features of two or more articles identified by Canadian scientists.
A team of Canadian researchers has for the first time identified a neurotransmitter that is crucial to the brain's ability to differentiate between the features of two or more articles-such as identifying a green apple amongst pears.
Leigh C.P. Botly and Eve De Rosa, psychologists at the University of Toronto, say that the neurotransmitter acetylcholine is key to the process of feature binding, by which our brain combines all of the specific features of an object and gives us a complete and unified picture of it.

Alzheimer's disease is a progressive neurodegenerative disease affecting memory and thinking and making the person increasingly dependent on others.

The researchers also developed a feature-binding task for rats (having them choose among variously scented food bowls) and treated some of the animals with the drug scopolamine, which temporarily blocks the effects of acetylcholine.
They found that patterns of behaviour were very similar in distracted humans and rats on scopolamine.
About Brain Tumor
Brain tumors are the abnormal growth of brain cells that may be benign or metastatic. Brain tumors account for about 2.4% of all the tumor diagnosesandare most challenging due to their critically delicate location.

The authors note that "acetylcholine may provide the attentional 'glue' for feature binding".
